Standalone library for working with spreadsheets and CSV in CFML

Project README

Spreadsheet CFML

Standalone library for working with spreadsheets and CSV in CFML (Lucee and Adobe ColdFusion), supporting all of ColdFusion's native spreadsheet functionality and much more besides.

Minimum Requirements

  • Java 8 or higher
  • Lucee 5.x or higher
  • Adobe ColdFusion 2018 or higher

Installation

Note that this is not an extension or package, so does not need to be installed. To use it, simply copy the files/folders to a location where Spreadsheet.cfc can be called by your application code.

The following are the essential files/folders you will need depending on which CFML engine you are using:

Lucee

helpers/
objects/
lib-osgi.jar
osgiLoader.cfc
Spreadsheet.cfc

Adobe ColdFusion

helpers/
javaLoader/
lib/
objects/
Spreadsheet.cfc

Usage

The following example assumes the file containing the script is in the same directory as the folder containing the spreadsheet library files, i.e.:

  • root/
    • spreadsheetLibrary/
      • Spreadsheet.cfc
      • etc.
    • script.cfm
<cfscript>
spreadsheet = New spreadsheetLibrary.Spreadsheet();
data = QueryNew( "First,Last", "VarChar, VarChar", [ [ "Susi", "Sorglos" ], [ "Frumpo", "McNugget" ] ] );
workbook = spreadsheet.new();
spreadsheet.addRows( workbook, data );
spreadsheet.write( workbook, "c:/temp/data.xls" );
</cfscript>

init()

When instantiating the library, the init() method must be called. This will happen automatically if you use the New keyword:

spreadsheet = New spreadsheetLibrary.Spreadsheet();

If using CreateObject() then you must call init() explicitly:

spreadsheet = CreateObject( "component", "spreadsheetLibrary.Spreadsheet" ).init();

Using a mapping

You may wish to place the spreadsheet library files in a central location with an application mapping, and instantiate the component using its dot path (e.g. New myLibrary.spreadsheet.Spreadsheet();).

How to create mappings (StackOverflow).

Supported ColdFusion functions

Extra functions not available in ColdFusion

Enhanced Read() method

In Adobe ColdFusion, the SpreadsheetRead() script function is limited to just returning a spreadsheet object, whereas the <cfspreadsheet action="read"> tag has a range of options for reading and returning data from a spreadsheet file.

The read() method in this library allows you to read a spreadsheet file into a query and return that instead of a spreadsheet object. It includes all of the options available in <cfspreadsheet action="read">.

<cfscript>
myQuery = spreadsheet.read( src=mypath, format="query" );
</cfscript>

The read() method also features the following additional options not available in ColdFusion or the Spreadsheet Extension:

  • fillMergedCellsWithVisibleValue
  • includeHiddenColumns
  • includeRichTextFormatting
  • password to open encrypted spreadsheets
  • csvDelimiter
  • queryColumnTypes

Full documentation of read()

Chainable syntax

From version 3, multiple calls can be chained together, simplifying your code into a more expressive syntax.

spreadsheet.newChainable( "xlsx" )
 .addRows( data )
 .formatRow( { bold: true }, 1 )
 .write( filepath );

More on chaining calls

Date formats

The following international date masks are used by default to read and write cell values formatted as dates:

  • DATE = yyyy-mm-dd
  • TIME = hh:mm:ss
  • TIMESTAMP = yyyy-mm-dd hh:mm:ss

An additional mask is used to output datetime values from the read() method into HTML or CSV formats:

  • DATETIME = yyyy-mm-dd HH:nn:ss

NB: Do not confuse DATETIME and TIMESTAMP. In general you should override the TIMESTAMP mask.

Each of these can be overridden by passing in a struct including the value(s) to be overridden when instantiating the Spreadsheet component. For example:

<cfscript>
spreadsheet = New spreadsheetLibrary.Spreadsheet( dateFormats={ DATE: "mm/dd/yyyy" } );
</cfscript>

Or by using the setDateFormats() method on an existing instance.

<cfscript>
spreadsheet = New spreadsheetLibrary.Spreadsheet();
spreadsheet.setDateFormats( { DATE: "mm/dd/yyyy" } );
</cfscript>

While the above will set the library defaults, you can format cells with specific masks using the dataFormat attribute which can be passed to formatCell and the other formatting methods, as part of the format argument:

// display datetime value with millisecond precision
spreadsheet.formatColumn( workbook , { dataformat: "yyyy-mm-dd hh:mm:ss.000" }, 1 );

JavaLoader

From version 2.14.0, Lucee loads the POI and other required java libraries using OSGi. This is not yet supported with Adobe ColdFusion which by default uses an included version of Mark Mandel's JavaLoader.

For more details and options see: Loading the POI java libraries

CommandBox Installation

You can also download this library through CommandBox/Forgebox.

box install spreadsheet-cfml

It will download the files into a modules directory and can be used just the same as downloading the files manually.

If using ColdBox you can use either of the WireBox bindings like so:

spreadsheet = wirebox.getInstance( "Spreadsheet@spreadsheet-cfml" );
spreadsheet = wirebox.getInstance( "Spreadsheet CFML" );

Test Suite

The automated tests require TestBox 5.0 or later. You will need to create an application mapping for /testbox

Credits

The code was originally adapted from the work of TeamCfAdvance. Ben Nadel's POI Utility was also used as a basis for parts of the read functionality. Header/Footer image functionality is based on code by Axel Richter.

JavaLoader is by Mark Mandel.
